R

If a definition for Rhotacism includes "the inability to or difficulty in pronouncing r.", why the fuck does it start with the letter "R"? Is this a joke?  Meant to ensure that those who have it cannot say it, leading to comedy when they try to explain their own speech?  A bit like Seinfeld on nosejobs, n'est-pas?

One of the most popular procedures today is the nose job. The technical term for the nose job is rhinoplasty. Rhino? I mean, do we really need to insult the person at this particular moment of their life? They know they have a big nose, that’s why they’re coming in. Do they really need the abuse of being compared to a rhinoceros on top of everything else?
